Beebe Hill wildflowers or “What the heck is that?”

So for all my talk about learning to “key” plants, I had a couple mystery finds on our hike up Beebe Hill on Saturday. I’m stumped by two flowers – even my new guide isn’t helping me out much. Cross-referencing guides only added confusion… is that bellwort or “wild-oats”? Here’s what we saw (click on photos to enlarge):

Coltsfoot seed head.

Mystery plant #1. Possibly garlic mustard?

Mystery plant #2. I would guess cinquefoil, but the leaves are wrong.

American dog violet

Bluets

We saw a ton of ferns – I can’t ID any of them.

Bellwort

Sedum – we found a lot of this near a very old foundation. I’m not sure it’s native.
